Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149390, here are decompositions:

13 + 149377 = 149390
19 + 149371 = 149390
67 + 149323 = 149390
103 + 149287 = 149390
139 + 149251 = 149390
151 + 149239 = 149390
193 + 149197 = 149390
229 + 149161 = 149390

Showing the first eight; more decompositions exist.
